Yesterday, SPB released SPB Mobile Shell for Windows Mobile 5 and according to this review from Aximsite, they’ve hit a home run! Mobile Shell enhances the WinMo interface with a nice screen called the "Now" screen which includes: the time & date, basic weather, battery charge, number of e-mails or voicemails and more. Also included is an efficient menu system, photo-based speed dialing and more for effective one-handed usage.
Probably the best overview to understand the product is the Aximsite review along with the demo video they put together. If you’re looking for more efficiency on your Windows Mobile 5 Pocket PC Phone Edition device, you’ll definitely want to see this!
